Cellulose Fiber Attic

Walls are patched up and painted over.

Cellulose fiber attic.

It is allowed to settle over time. Attic card greenfiber provides outstanding thermal performance fire resistance and sound control. Rather than trying to meticulously lay fiberglass insulation over the attic homeowners and builders can simply blow cellulose insulation throughout the attic. When using cellulose blown in dry insulation it requires a machine to achieve its purpose and a training session from wherever you rent the blower from.

The trapped air molecules in the insulation are pulled up through the insulation into the colder attic air. 2 as demonstrated by the large scale outdoor fire test program comparing. 1 an uninsulated structure. The cellulose is allowed to fill the cavities or blanket existing insulation.

The cellulose is blown into the attic or walls through long flexible tubes that run from the blower to an application nozzle. Or 7 inches of cellulose. The air trapped in the pockets of the insulation is part of what insulates your home. This problem has been successfully solved by installing fiberglass batt insulation over the top of loose fill or blown insulation.

Fiberglass insulation is the easiest insulation product on the market to install and if installed correctly the most effective product on the market for home attic insulation. Cellulose is more difficult to cheat than fiberglass. Consisting of up to 85 recycled content greenfiber insulation is specially treated for flame resistance. When used in an attic space however both types of insulation are ineffective at air flow across the attic floor such as a strong gust of wind.

The two main least expensive and most commonly used residential insulation materials is cellulose and fibreglass. You can get to the same place with either material. The bottom line is that cellulose can burn but fiberglass will not support combustion. R value means resistance to heat flow the higher the r value the greater.

2 a structure insulated with r 13 fiberglass batts wall cavities and blown in loose fill insulation attic floor. Cellulose forms a dense continuous mat of insulation in your attic. So what are the advantages and disadvantages of each of these. This keeps the air from moving within the insulation and from penetrations between the air conditioned space and the attic.

Both cellulose and fiberglass need to be installed at the correct depth and density to achieve the intended r value. Assuming your current attic insulation is made from fiberglass and has a value of r 13 you d have to add roughly 10 inches of additional fiberglass to hit r 38. Blown cellulose is typically the preferred choice of insulation for attics. No pressure is placed on the cellulose.
